How to enable guest network on Tenda routers? Relatives stayed for a week without providing the mainnet password, and the app could automatically shut it off at scheduled times
spent last year's National Day at my mother-in-law's house. My brother-in-law's family and my cousin's family all came back. The four kids ran around the house clutching their phones and tablets, and the first thing they did upon entering was to ask for the WiFi password. My mother-in-law couldn't remember the password and blamed me, so I reported the 10-digit password one by one. Eleven devices in total, children's games, and adults' short videos were all posted on the main website.
November, my mother-in-law called to say the internet speed card was missing, and the video calls were all blurred with mosaics. I remotely had her access to the backend devices. Wow, there were only six at home, but nine were listed on the list, and three more were unfamiliar phones—two of which belonged to the upstairs neighbor. How did the password get out? Most likely, some child's phone has a master key, and the connected WiFi is automatically shared. I wrote about this in my article about anti-internet access. Using a 16-digit long password at home can block most openings, but the root problem is— mainnet password, you shouldn't report it to the customer's . The WiFi password is equivalent to half a home key. I mentioned this in my about changing WiFi names. Router background apps, file sharing, screen casting—all recognize this key.
this year's National Day hasn't arrived yet, I already set a plan in advance: to set up a visitor network for my mother-in-law's Tengda machine. The customer even leaked a single word of the client's own web and main network password. Along the way, I discovered a feature I didn't know about last year—the app lets you disable the visitor network settings and automatically disconnect when needed, so no one needs to remember to finish them off. The whole trip was much easier than last year, so I'm writing the whole process for everyone.
What kind of network is
visitor network: you can get out through the door, but you can't get inside
first explain it clearly, otherwise the subsequent operations will be confused. The guest network isn't a second router, nor is it a second broadband—it's just your Tengda Duo broadcasting a WiFi name. Customers can connect to this network and still be online, watch videos, and play games—there's hardly any difference in experience compared to connecting to the main network.
missing is the door of the 'inner room.' There is a wall by default between the visitor network and the main network: the guest's phone cannot access the management backend 192.168.0.1, cannot access the storage and sharing files you have on your network, and features like screen casting and printers that can be found through LAN connections are basically impossible to find. When I set up the visitor network for my Mercury at home, I tested every border one by one. The internet worked fine, but the background couldn't be accessed, and the NAS couldn't be accessed. Tenda's rules are the same. So opening this network for guests isn't just about preventing master keys, but also about preventing suspicious apps from browsing your internal network.
in short: the mainnet is your own key, while the visitor site is the temporary lobby card. Temporary cards are ready to be closed when needed, which is the purpose of scheduled shutdowns later.
Three steps
tendawifi.com to launch a dedicated customer website
operation is simpler than expected. Connect your phone to the router's WiFi, type tendawifi.com in the browser's address bar (192.168.0.1 will also work, same door), enter the management password to enter the backend. If you forget this password, you'll have to go through the factory restoration route, which comes at a high cost. I wrote about it before in the about the Tengda reset, so don't rush to act yet.
After
the backend, tap "More Features," then find "Wi-Fi Settings," where you'll find the "Guest Network" section. The interface of the old firmware is different; the menu is compressed into the wireless settings section, and the name might just be Guest WiFi. You can always find it after a few clicks. Press the switch and set two things: the name and the password.
I named it 'Exclusive for Guests'—it's instantly recognizable, and it's easy to explain when customers ask—including this and not that. The password is set separately as 8 digits, completely different from the mainnet password. Here's a little tip: don't try to save effort by entering the mainnet password exactly as is, or it's wasted. An eight-digit number plus letters is enough for a customer to use for a week. Anyway, once the password is closed after the holiday, it's invalid and you'll have to replace it the following year.
save, try connecting it to your own phone. If you can access the internet and send via WeChat, it means the app is open. Try another boundary: connect to Visitor Network to enter 192.168.0.1, and you can't access the backend, that's the correct way—that wall is working.
The timer shutoff in the
App was something I only discovered this year
Last year, the Tenda at my mother-in-law's house was operated through the web backend. This year is different—I installed the Tenda WiFi app on my phone and tied the router. Binding is important: you can only bind it when you're in front of the router or with your phone connected to its WiFi. If you can't bind it, go through the App binding troubleshooting article check them one by one. Ninety percent are stuck because of the wrong WiFi connection or outdated firmware.
After binding the
, tap the router on the app homepage. In the Wi-Fi settings, you'll find the guest network switch, so you can turn it on wherever you are. This "anyone can be anywhere" is the key point—on the fifth day of National Day, we first returned to the city. My brother-in-law and the others stayed two more days and brought friends, and my mother-in-law called to ask how to connect to the internet. Last year, I had to recite for half a day; this year, just a couple of orders in the city opened the visitor website, and my mother-in-law just wanted to let guests enjoy the "guest exclusive."
real treasure is the timer closing beside it. The biggest problem with the visitor network running wasn't the fact that it was on, but that the customer left and it stayed on—my Mercury didn't have this feature, so I had to rely on someone to remember and turn it off. In the Tenda app, you can set it to automatically stop after a few hours. I set it to 4 hours, enough for a meal plus an afternoon pass, and the card will automatically discard when the time comes. If the customer in the middle wants to renew, just tap the switch again, which is much cleaner than letting them know the mainnet password.
note: this timed shutdown is for the guest network, and it's a different thing from the 'WiFi timer switch' for whole-house shutdown. I wrote about the latter in my article about Tenda's scheduled disconnect for the main network, so don't mix it up.
three pitfalls: the child's tablet is paired with the wrong network, guests have to cast their screens, and speed limits don't keep up
The first pitfall is smart device networking. The name of the visitor network is different from the mainnet. If any devices at home that only recognize 2.4G connect to the visitor network by mistake, once the network is turned off, they will all lose contact. My brother-in-law's child's story device is like this: when setting up the network, someone's phone at home casually connects to Visitor, and the story machine is installed accordingly. The next day, the story device goes offline, and after searching for a long time, I found it was listed under 'Guest Exclusive.' The tips for smart device network setup, the failed network setup , are fully covered. The core is: before configuring the network, make sure your phone is connected to the main network.
second pitfall is that customers have to cast their screens. With the TV on, customers want to upload photos and videos from their phones, but after searching for a long time, the device can't find it—the visitor network and mainnet are separated by walls, and casting features that rely on LAN can't be managed. My method is simple and direct: send the photos to family members' phones via WeChat, and have the devices on the main network post them. If you often need to cast your screen to customers, then you need to weigh your options before building the wall.
third pitfall is speed limits. Four kids each play on their own phone at night, and there's no separate speed limit switch on the visitor network (I checked the guest settings on my AX12 to see if it's missing at all), and the mainnet TV is a bit laggy. My backup plan is to enter device management, limiting downlink to the phones of those kids by device—50MB per device. Enough for games and videos without blurring, and the operation is the same as from Tengda's speed limit post on . If you're concerned about internet time and not speed, then you should use parental control create groups and draw time grids, not just the speed limit.
is not worth opening under any circumstances or circumstances
Not every household has to open one. Guests only come once or twice a year, or can't stay for two hours. It doesn't matter if you give your password—just change it back later. The following situations are worth opening: relatives staying for more than two or three days; Among the guests are half-grown kids; you don't care what is on your phone; The home network is filled with storage and cameras—things you don't want to be rummaged through; Or perhaps they already suffered losses last year due to password leaks. Mother-in-law's family occupies all four strips; if you don't open them, you're truly bold.
Wrap up in a sequence, follow it in ten minutes to finish: first install the app and bind the router (you must be at home); Then go to the backend to open the visitor network, set an independent name and password; Connect your own phone to the verification network; you can get online, but can't access the backend; Set a timed shutdown for the visitor network; Guests arrive and connect directly; The person was exposed, then glanced back to check—the switch was off. Next year, when guests come again, just change the visitor password—it's just a matter of a minute.
mainnet password hasn't been reported this year, all 11 customer devices are on a network that disconnects after use, and those three unfamiliar phones haven't appeared again this year. There was another unexpected gain for the mother-in-law: she finally didn't have to remember two passwords—the mainnet one was stored on my phone, and she only connected to the "guest exclusive" service.
